blas question

[Robert H. Miller]

I am attempting to use the cblas via gsl.

int  gsl_blas_dgemm (CBLAS_TRANSPOSE_t TransA,
                     CBLAS_TRANSPOSE_t TransB,
                     int K,
                     double alpha,
                     const gsl_matrix * A,
                     const gsl_matrix * B,
                     double beta,
                     gsl_matrix * C);

and
int  gsl_blas_dgemv (CBLAS_TRANSPOSE_t TransA,
                     double alpha,
                     const gsl_matrix * A,
                     const gsl_vector * X,
                     double beta,
                     gsl_vector * Y);

I am having a hard time figureing out what the CBLAS_TRANSPOSE_t TransA
is exactly.  I assume it is just a flag to indicate transpose?

enum CBLAS_TRANSPOSE  { CblasNoTrans=111,  CblasTrans=112,  
CblasConjTrans=113 };

So if I put a zero in the first arg I should just get
y<-alpha A x + beta y??


Thanks
